I really enjoy shooting and carrying the 45 acp. I will give my top three reasons, please tell us your top three reasons. 1. It is accurate, I shoot it better than other cartridges 2. It performs its ballistics without alot of fuss, recoil is mild compared to higher pressure big bore rounds. Bullet weight and diameter do not diminish, velocity does. The 45 acp does not require high pressure or high velocity to do its job. 3. It is a cartridge that I can carry concealed yet deal with outdoor 4 legged threats in the woods but also jump in the truck and get supplies in town to deal with potential 2 legged threats without changing my carry gun. I just change ammo from hardcast to jhp. Easy. Note I do carry big bore revolvers when hunting and micro 9's when I need the deep concealment. So I am not anti other cartridges.
